Patent JP-H02155399-A (JP)
Title: Speaker unit
Inventor: SHINGO TAKAYUKI
IPC: H04R7/20
Filed: 1988-12-07
Abstract: PURPOSE:To adjust a low frequency range to a preferred frequency range by forming at least one of an edge and a dumper with a hardness variable member whose hardness is varied with heat and a conductive heater and connecting a variable resistor adjusting a current flowing therethrough to the heater. CONSTITUTION:A current flows from a power supply 9 to a conductive heater 1b of an edge member 1 through a variable resistor 3 and a speaker interconnection cable 10. When the current flowing to the conductive heater 1b is increased to raise the temperature of the heater, an upper layer edge section 1a and a lower layer edge section 1c in contact with the conductive heater 1b are heated, the hardness is decreased and the minimum resonance frequency f0 is lowered. Moreover, when the current is limited, the temperature of the conductive heater 1b is decreased, the hardness of the upper layer edge section 1a and a lower layer edge section 1c is increased and the minimum resonance frequency f0 is increased. Thus, the user can adjust the minimum resonance frequency f0, that is, the low sound frequency as its own preference by adjusting the variable resistor 3.

Title: Protecting device for converter
Inventor: AOYAMA FUMIO
IPC: H02M7/155
Filed: 1989-11-30
Abstract: PURPOSE:To minimize the current limiting protecting operation of a fuse by a method wherein short circuit current is interrupted by a GTO(gate turn-off thyristor) which is immediately turned OFF upon occurrence of DC short-circuit fault. CONSTITUTION:When an OFF signal is supplied before turn-off of a GTO after providing the GTO with an ON signal, there is the possibility of breakage of the GTO. When DC short circuit happens before turn-off of the GTO 11A after providing the GTO 11A with an ON signal, the retension of energizing condition of the GTO is continued and a short circuit current is intercepted through fusion of a fuse to prevent the breakage of the GTO 11A. Further, when the DC short circuit is occurs after the GTO 11A is provided with the ON signal and the turn-off of the GTO 11A has been finished perfectly, the GTO 11A is provided with an OFF signal forcibly and the short-circuit current is intercepted by the function of the GTO 11A to protect the same.

For example, the coexistence ratio of the uniform states and the twisted states is set at 10 to 60% in the twisted state. The twisted states change to the uniform states when a prescribed electric field is impressed to the orientation state in which the uniform states and the twisted states coexist. The relative treatment angle in the orientation treatment direction between the transparent substrates 11a, 11b is set at 0 to 20 deg. at the time of subjecting the orientation control films 14a, 14b deposited on the transparent substrates 11a, 11b to orienting means.

In addition, a reference power spectrum(RPS) is displayed by using an algorithm and stored in a memory. Similarly, a current power spectrum(CPS) is taken in real time, compared with the RPS by using a pattern recognizing algorithm so that the change may be noticed by the operator, and indicates the change of the flowing form in a specific nozzle for correction.  In addition, the presence of an unstable flow during measuring time is detected by using the analysis of the temporal change of a real-time signal from the sensor of the accelerometer 5.

Filed: 1992-11-20
Abstract: PURPOSE:To provide an inexpensive receiving antenna which can receive the signals from plural satellites without using plural primary radiators by collecting the signals received from the satellites of different positions by means of a frequency selecting reflector or a polarized wave discriminating reflector. CONSTITUTION:A frequency selecting reflector 2 reflects only a signal of the specific frequency out of the signals 6 of different frequencies received from the satellites 4 and 5 set at different positions in the direction of a primary radiator 3 with resonance secured with a pattern formed on a mirror surface. Meanwhile the reflector 2 transmits the signal 6 of another frequency received from the satellite 4 set at a different angle with no resonance. Then the transmitted signal 6 is reflected toward the radiator 3 set at the same position by a reflector 1 having an angle different from the reflector 2. Under such conditions, the reflector 2 can be produced at the cost lower than that of the radiator 3 consisting of combined parts. For this purpose, a ring-shaped or lattice line- shaped conductor pattern is formed by printing, etc., to a dielectric of plastic which is produced by molding.

IPC: G03G15/16
Filed: 1992-11-20
Abstract: PURPOSE:To stably discriminate whether the recording paper sheet of a printer is ordinary paper or OHP paper, and improve image quality in using the OHP paper. CONSTITUTION:An OHP sensor 56 serves as a reflection-type photosensor is disposed near the front of the third paper feed roller 53. The OHP sensor 56 discriminates recording paper based on the level of reflected light quantity from the recording paper. An interval between carrier guide plates 54, 55 is set so that the recording paper can exist within an distance area where detection accuracy by the OHP sensor 56 can be ensured even if the recording paper waves. A through hole through which the light transmitted through the recording paper passes is formed at the carrier guide plate 55 to prevent the light transmitted through OHP paper from reflecting at the carrier guide plate 55. With the above constitution, transfer current is increased, linear velocity of fixing is decreased, and paper discharge is made smooth when the paper is discriminated to be the OHP paper.
